IMPROVEMENT IN GRINDING-MILLS.

Specification forming partofl etters Patent No. 105,448, dated July 19, 1870.

To all whom/it. may concern.- a a "Be it known that IfDANIELHALLADAY,

of Batavia, in the county of Kane and State of Illinois, have invented an Improved Grinding-Mil l; and Ijdo hereby declare that the following is afull and exact description thereof,"

which will enable those skilled in the art to make anduse the same, reference being had L to the accompanyingjdrawings and letters marked thereon, making apartof this speci- 1 fication, in whichf I Figure lis a perspective representation of my improved grinding mill; Fig. 2, a plan or top view of the same;rFig. 3, a perspective representation of the combined lower case and invention relates to what is nature consists in the novelconstruction of the spout, as combined with the lower case, the

arrangement being such that the spout can be placed parallel: and at right angles with the drive-shaft for'theconvenien cc of discharging the ground substance.

1 Theframe consists of inclined standards N a and a rectangular cross/tree, N, saidframe being, as shown, conveniently arranged to supportthegrindingdevi'ceshereinafterdescribed.

An upper bridge-tree, N, is also a part of this framework, fastened to the standards N, and

it, in the ordinary manner, supports the gearing a b 0, for-driving the grinding-plate Q, in the usual manner. Nothing, however, is claimed to, be new in the said frame, the above description being given simply to enable othersto build the mill on the-most economical plan. I

d represents a vertical spindle,'which passes 'throughthe cross-tree N, and has a bearing or, step in an adjustable lever, e. Thislever I is jointed to the cross-tree N. at f, audit is so adjusted, by means of a set-screw and screwrod, g, Fig. 1, that (the said spindle may be conveniently raised and lowered in order to bring the grinding-plate Q properly up to the grinding-case D, so that grain may be ground I to any desired degree of fineness.

Above the gearing a'c, andbeneath the grindingplate Q; is placed a case, B, which case may require.

has a flange extending up to the grinding-case D, to whichit is secured by means of two or more clamps, O, and nuts F, Fig. 1; The grinding-case D is provided with arms H, which rest upon the tops of standards N, and are so I I. Fig. 2,,so as to bring the spout I between any two of the standards N, except those two-next the drive-pulleyb. This arrangement is made for the convenience of discharging the ground substance where it can be best disposed of.

On the flanges or sides of the spout, at J, are made notches, in orderto support the lower part of a cover, G, which is held in place at its upper edge by extending under the grinding-case. The-object of this cover is to prevent the ground substance from being 'thrown out of the spout and getting into the gearingof the mill: or wasted,'and as the mil l is to be made of metal, thepresent manner of arranging the spout, lower case, and cover is very convenient and simple, as is also the means for raising the. spindle d, as it is arranged ,with reference to the frame and lever e.

In the foregoing it will be seen that the entire mill has been described, so as to enable others to fully comprehend the construction and position of the spout,

Having thus described my invention, what I claim, and desire to secure by Letters Patent 7 of the United States, isi The reversible spout I, arranged with a lid,

G, which fits into notches J, in combination with the grinding-case B D, when arranged V with reference tothe grinding-plates and other parts of the mill as set forth.
